Stretch marks are streaks that appear when the skin expands fast, which is commonly caused by weight gain, pregnancy, or growth spurts. They begin as red or purple lines that fade to white with time. Maintaining a healthy weight, moisturising on a regular basis, staying hydrated, and eating a vitamin and mineral-rich diet are all preventative methods. Topical retinoids and laser therapy are two early treatment options that might help lessen their appearance.
